Synthesis and characterization of ring-type and branched polymers including polyethylene glycols by “click” chemistry [PDF]

open access: bronzeSN Applied Sciences, 2019
Synthesis of ring-type (or branched) polymers including polyethylene glycols was archived via “click” chemistry of 5,6-diazido-2-benzyl-1H-benzimidazole (Di-N3) [or triazidoacetohydrazide derivative (Tri-N3)] and terminally dipropargyl polyethylene glycols (PEG-dipropargyl) with different molecular weights.

Hyperbranched Polymers with High Degrees of Branching and Low Dispersity Values: Pushing the Limits of Thiol–Yne Chemistry [PDF]

open access: greenMacromolecules, 2016
We propose a versatile approach to the production of hyperbranched polymers with high degrees of branching and low dispersity values (Đ), involving slow monomer addition of a thiol/yne monomer to multifunctional core molecules in the presence of photoinitiator and under UV irradiation.

Hyperbranched polymers with step-growth chemistries from transfer-dominated branching radical telomerisation (TBRT) of divinyl monomers

open access: hybridPolymer Chemistry, 2020
The commercially relevant synthesis of novel materials with step-growth backbones has been achieved by applying conventional chemistries to the radical telomerisation of divinyl monomers leading to high molecular weight branched polymers.

Dendrimers: Branching Out of Polymer Chemistry

open access: closedJournal of Chemical Education, 2002
Intended for undergraduate students of organic chemistry, this article addresses synthetic concepts surrounding dendrimers, including the use of protecting groups, functional group interconversions, and convergent and divergent synthetic strategies. The review concludes with some of the elementary synthetic transformations used to construct dendrimers.

Molecular engineering of branched polymers through 1,1-diphenyl-ethylene chemistry and anionic polymerization

open access: closedEuropean Polymer Journal, 2015
Abstract In this feature article, we describe the synthetic work in our laboratory on branched polymers through anionic polymerization reaction based on selective addition of organolithium toward a bifunctional 1,1-diphenylethylene derivative, 1,3-bis(1-phenylvinyl)benzene (MDDPE).

Convergence of DNA Nanotechnology and Polymer Chemistry to 'Synthesize' Nanopolymers with Branching Architectures: A Computational Perspective

open access: closedSoft Matter
We propose a polymerization-like protocol to program coassembly of DNA-functionalized mixtures into non-linear superstructures with well-defined branching architecture and predictable spatial dimensions.
